Hitherto our knowledge of what happened between the Rivers Oder and Dniepr from AD 965 to AD 1480 has come largely from western sources. This English translation and abridgement of Jan Dlugosz' Annales seu cronici incliti regni Poloniae, a medieval chonicle ranked on the level of those of Froissart and de Commynes, opens up the history of Eastern Europe to the non-Polish reader. The abridgement is on the basis of readability and the text contains a number of interesting stories, such as that of a tramp revealed in death to be a secret royal courier.
